PLEASE HELP THANK YOU SO MUCH Consider the statement. The sum of two irrational numbers is always an irrational number.
Is the statement true or false? Justify your answer.
true; Irrational numbers are closed under addition: + 27 = 37.
false; Only division results in irrational numbers. All other operations on real numbers give rational numbers.
true; The sum of two irrational numbers is a rational number, which is also an irrational number since all rational numbers are also irrational
numbers.
false; Irrational numbers are not closed under addition: V14 + (-14) = 0.

number one is the correct answer

step-by-step explanation: dogs and cats are mentioned, no other animals

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

i belive those are the ones that are under 90 degreese.

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
